The article discusses the species and taxonomic composition of the long-eared owl (Asio otus) preys based on the analysis of pellets (n = 209) collected in the winter-spring period in 2016 in the Malarytsky district (Lozitsa village) and the Brest region district center. The distance between Malaryta town and Lozitsa village is about 10 km. Parts of the skull of 512 small mammals (2.45 individuals per pellet) and one bird were found. Feeding on birds for the long-eared owl is episodic. Representatives of 2 orders, 10 genera and 12 species of small mammals (5 species of shrews and 7 rodents) became preys of the owl. The proportion of rodents is 98.24 % of all preys. The absolute dominant among prey species is Microtus arvalis (85.16 % of all victims), which is consistent with numerous work carried out in other regions. Significant portions are of Apodemus agrarius (4.10 %), Muscardinus avellanarius (2.54 %), Sylvaemus tauricus (1.76 %), and Alexandromys oeconomus (1.56 %). The list of preys is presented by meadow-field, synanthropic and different species actively moving from adjacent forests in the Malaryta river floodplain and canal systems (Sylvaemus tauricus, Sorex araneus, S. minutus, Neomys fodiens). The occurence of two shrew species Crocidura leucodon and C. suaveolens in the city of Malaryta has been proved, which corresponds to similar information for the city of Brest. This suggests that C. suaveolens inhabits the entire territory of the Belarusian Polesie at present. The occurence of the non-abundant species Sicista betulina in vicinities of the town of Malaryta was confirmed. The results obtained confirm the significant trophic effect of the long-eared owl on the local population of the hazel dormouse and also indicate the relatively high abundance of this rodent in the study area. Seven species were identified in pellets of the long-eared owl living near the village of Lozitsa, and 12 species of small mammals were identified in the town of Malaryta. The diversity of the landscape of the town of Malaryta determines the large number of prey species.

This article deals with the results of study of species content and basic peculiarities of beaked mites-Phytoseiidae in plant associations of one of the regional centers of Ukraine. The species composition and distribution of mites-Phytoseiidae (Parasitiformes, Phytoseiidae) in plantations of Brovary town of Kyiv region were determined. Fourteen species of 8 genera of phytoseiid mites were found. Index of their existing and relative biotope connection of each registered species to vegetation types and plant species were computed. The study was conducted according to the results of material treatment on the territory of the mentioned city from 25 species of plants (16 species of hardy-shrub and 9 of herbaceous vegetations). The studies of distribution of plant-living mites-Phytoseiidae were conducted separately for hardy-shrub and herbaceous plants). The collection of faunistic material was executed during the vegetation of periods of 2011 and 2013. Within the city the collection of the material was conducted with hardy-shrub plants and herbaceous type of vegetation along the streets, in parks and squares of Brovary city of Kyiv region, district center, one of the satellite-cities of Kiev, the capital of Ukraine. The study of species complexes characteristics of mites was conducted with usage of data calculated on the basis of frequency index (Is), degree of relative habitat confinedness (F) (Pesenko, 1982) and domination index Paliy-Kovnatski (Di) (Shitikov, 2003). Only on one species of plant (F=1) 6 species of mites-Phytoseiidae were found – T.сotoneastri on blue spruce, T. laurae – on common spruce, T. aceri – on ash-leaved maple, P. incognitus – on dog-rose, P. soleiger – on mulberry-tree, A. caudiglans – on sea-buckthorn. These species can be related to stenoecic. The mentioned species are stenotopic only in relation to the sample of plants from the plant associations of Brovary, as in other regions these species of mites can populate the other species of plants. The rest 8 species, being registered on two or more types of plants, are related to euryoecic. Among them there is a group of 6 species with “positive tendencies to population of plants”, owning the indicators of habitat confinedness 0<F<1: A. andersoni (0,92–0,96), A. rademacheri (0,85–0,96), N. herbarius (0,92–0,96), T. tiliarum (0,66–0,77), A. pirianykae (0,73–0,99), A. clavata (0,82–0,98). The rest species, E. finlandicus и K. aberrans, have the expanded range of indicators in relation to habitat confinedness (-0,71<F<0,55 и -0,16<F<0,88), that specifies on their ability to populate the big quality of species. E. finlandicus has the negative indicator of relative habitat confinedness in relation to the plants of herbaceous morphotype that serves confirmation of the ecological peculiarity of the species detected earlier. The data of relative habitat confinedness of mites to certain species of plants shows availability of stenoecic (T.сotoneastri, T. laurae, T. aceri, P. incognitus, P. soleiger, A. caudiglans) and euryoecic species (A. andersoni, A. rademacheri, N. herbarius, E. finlandicus, K. aberrans, T. tiliarum, A. pirianykae, A. clavata).

The latest special studies of the genus Synura in Russia were conducted in the 1970s. In the last decade, 14 new species of the genus were described based on molecular and morphological data. The total number of valid taxa of the genus has increased to 49. Only 18 taxa of Synura are known in Russia up to date, and the diver sity of the genus on this huge territory is strongly underestimated. Previous studies of the genus were focused mainly on large lakes or reservoirs. To reveal a more complete flora, it is necessary to include other habitats into account. Small urban rivers can be prospective habitats for interesting taxa including synuralean algae. Our study focuses on the taxonomic composition of the genus Synura in four small rivers in Nizhniy Novgorod (European Russia): Chyornaya, Levinka, Borzovka and Rzhavka. All the rivers flow in the city and fall under strong anthropogenic impact. The genus Synura was studied by means of transmission and scanning electron microscopy during 2011, 2012, 2014, 2015. In total, eight species and one form of Synura have been found: S. conopea, S. curtispina, S. echinulata, S. glabra, S. macropora, S. petersenii, S. spinosa f. spinosa, S. spinosa f. longispina, S. uvella. All nine taxa were observed in the river Chyornaya. Five taxa were found in the rivers Levinka, Borzovka and Rzhavka. One species (Synura conopea) is a new record to the flora of Russia. It was found in all studied rivers. Four taxa (S. conopea, S. glabra, S. macropora, S. spinosa f. longispina) are new records to the Middle Volga river basin.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

Dominique Iogna-Prat’s latest book, Cité de Dieu, cité des hommes. L’Église et l’architecture de la société, 1200–1500, follows on both intellectually and chronologically from La Maison Dieu. Une histoire monumentale de l’Église au Moyen Âge (v. 800–v. 1200). It presents an essay on the emergence of the town as a symbolic and political figure of society (the “city of man”) between 1200 and 1700, and on the effects of this development on the Church, which had held this function before 1200. This feeds into an ambitious reflection on the origins of modernity, seeking to move beyond the impasse of political philosophy—too quick to ignore the medieval centuries and the Scholastic moment—and to relativize the effacement of the institutional Church from the Renaissance on. In so doing, it rejects the binary opposition between the Church and the state, proposes a new periodization of the “transition to modernity,” and underlines the importance of spatial issues (mainly in terms of representation). This last element inscribes the book in the current of French historiography that for more than a decade has sought to reintroduce the question of space at the heart of social and political history. Iogna-Prat’s stimulating demonstration nevertheless raises some questions, notably relating to the effects of the Protestant Reformation, the increasing power of states, and the process of “secularization.” Above all, it raises the issue of how a logic of the polarization of space was articulated with one of territorialization in the practices of government and the structuring of society—two logics that were promoted by the ecclesial institution even before states themselves.

In the discussion of Greek dramatic origins, a curious passage of Apuleius has never, so far as I know, been mentioned.In the second book of the Metamorphoses the hero Lucius describes a feast given at Hypata in Thessaly by his rich relative Byrrhena. After the feast Byrrhena informs him that an annual festival, coeval with the city, will be celebrated next day—a joyous ceremony, unique in the world, in honour of the god Laughter. She wishes that he could invent some humorous freak for the occasion. Lucius promises to do his best. Being very drunk, he then bids Byrrhena good-night, and departs with his slave for the house of Milo, his miserly old host. A gust blows out their torch, and they get home with difficulty, arm in arm. There they find three large and lusty persone violently battering the door. Lucius has been warned by his mistress, Milo's slave Fotis, against certain young Mohawks of the town—‘uesana factio nobilissimorum iuuenum’—who think nothing of murdering rich strangers. He at once draws his sword, and one by one stabs all three. Fotis, roused by the noise, lets him in and he quickly falls asleep.

abstract On 28 July 1981 at 17:22 UTC, the Kerman province of southern Iran was shaken by the largest and the most destructive earthquake in its history. Its surface-wave magnitude was about 7.2. The epicenter of the earthquake was located about 45 km southeast of the city of Kerman, the capital of the Kerman province. The shock killed nearly 3,000 people, left more than 31,000 homeless, and destroyed virtually all buildings in the epicentral region within a radius of 30 km. The hardest hit place was the town of Sirch where about 2,000 people died out of a population of 3,500. Surface fractures were observed in several areas, and the earthquake was apparently associated with a fresh surface normal faulting. The maximum vertical displacement was about 1 m. The maximum width of the fracture was 0.5 m. Also, extensive landsliding and numerous rockfalls were observed within the area of maximum damage. Most houses in the epicentral area are of adobe construction, made of sundried clay brick walls, and heavy domed roofs or vaults with clay or mud mortar. Most casualties were due to the collapse of these adobe buildings. However, the performance of unreinforced or reinforced brick buildings, historical monuments, steel buildings, and other types of structures during the earthquake is also discussed in this paper.

Experiments in Colorado and New York streams assessed the effects of predaceous stoneflies on benthic invertebrate community establishment in enclosures providing uncolonized habitat. Aspects of prey community structure measured were density, species richness, relative species abundance, and body size. Unexpected inorganic sediment deposition allowed evaluation of direct effects on Colorado stream benthos and indirect effects on predation. Predaceous perlids and perlodids consistently reduced the density and, therefore, rate of prey community establishment in enclosures. Although New York perlids disproportionately reduced densities of some prey species, Colorado stoneflies caused nonsignificant declines in individual prey species densities, the composite effect of which was a significant whole-community response. Predators did not affect prey species richness nor change the taxonomic composition (species additions or deletions) of communities colonizing enclosures. However, the relative abundance of prey taxa differed significantly between cages with and without predators. Most species showed no size differences between individuals colonizing enclosures with predators and those colonizing control enclosures, with a few interesting exceptions. The deposition of silt eliminated the predator effects on prey density, as well as directly causing significant reductions in many Colorado benthic populations. This result demonstrates that abiotic disturbances can periodically override the effects of predation on stream insect communities colonizing enclosures.

This article deals with the situation of the Jews in 1654 at the beginning of the Muscovite invasion of the Polish–Lithuanian Commonwealth. It is maintained that that was the main reason to the disasters that befell the Jewry of the Grand Duchy of Lithuania. The extant sources (mainly relating to Vilnius) show that in the occupied western lands of the GDL the attitude of the Russian authorities towards the Jews was more relaxed than in the eastern lands inhabited by the Orthodox. Seeking to win the favour of the population of the occupied territory, the Russians tried the Jews and the Christians by the same laws at least in areas where their jurisdiction was introduced. That could mean that Muscovy had no definite programme concerning the Jews at least in the western part of the GDL, inhabited mainly by the Catholics. Meanwhile, the Jews, despite the hostile attitude of the local population – that was attested by the plea of Vilnius authorities to the tsar to evict the Jews from the city – managed to find a way of coexistence both with the locals and the authorities of the occupiers. The sources show that even after the tsar’s indication to remove the Jews they continued to reside in the city.

The article deals with the problems of post-war reconstruction of Yalta – one of the most popular resorts of the Soviet Union. During the great Patriotic war, this all-Union health resort was subjected to barbaric destruction and looting. The fascist occupation regime (1941-1944) caused enormous damage to the health resort Fund of Yalta, the city economy and the entire infrastructure of the southern coast of Crimea. The rapid return to the pre-war structure and the commissioning of social facilities has become a priority for the regional authorities and the population. In addition to traditional methods, the Patriotic «Сherkassov» movement, which began in the liberated Stalingrad in 1943 and spread throughout the country, was widely used. A solid Foundation was laid for the interaction of the city administration of Yalta and the local population with the commanders and soldiers of the red Army. Based on the analysis of archival documents of the State archive of the Republic of Crimea, it was possible to trace the course of restoration work in the fi rst months after the liberation of the Crimean Peninsula from fascism. It is established that for the rapid restoration and functioning of the Yalta resorts, public activists launched a socialist competition on «Сherkassov» methods
